are kept and the brushes referred to are those held by the container caso that they are immersed in the liquid in the container when the cap isin place on the container.

One of the objects of the invention is to provide "a container having ascrew cap thru which an applicator brush extends, these parts "beingarranged so that the brush is sealed fluid tight in the cap when the capis tightened on the container top.

Another object is to provide a container having a threaded top openingand a sealing cap threaded thereon together with a liquid applying brushhaving a cylindrical handle inserted thru said cap and verticallypositioned by a rigid compression piece held within the lower inner partof the cap, and a ring of resistant material compressed between the captop and the compression piece so that the brush handle is sealed fluidtight in the cap and so that viscous substances clinging to said brushhandle will be scraped oil when the brush handle i drawn upward thru thecap.

Another object is to provide a container with a screw top and a brushinserted therethru arranged so that the brush may be drawn upward thruthe cap and will be retained at any desired verticalposition relative tothe cap.

Still another object is to provide a screw cap for a container having aconical protrusion sur rounding a brush handle hole in its top, and arigid compression piece fitted in the under side of the cap held by asealing washer and having a conversely extending conical protrusionsurrounding a similar hole, with a ring of resilient material positionedbetween the cap top and said compression place; all being adapted toscrew, fluid tight, on a container top and to receive and retain a brushhaving a handle extending thru the holes in said cap and retainer sothat it will be free to move axially but will be retained, fluid tight,in any desired longitudinal or rotative position.

Other objects will appear hereinafter.

We attain the foregoing objects by means of the device and constructionshown in the accompanying drawings in which:

Figure 1 is an elevational view of a container embodying our cap andbrush holder;

Figure 2, a vertical section of the top portion thereof;

Figure 3., a plan viewof the rigid retainer contained within the-cap;

Figure 4, a side elevation thereof,and

Figure 5., a :plan View of the resilient sealing ring held within thecap.

Similar numerals of reference indicate similar parts in the severalviews.

The container 12, which in this example is a bottle, is provided with athreaded neck top 3. A cap of metal or other suitable rigid material 4screws onto this neck top. The top of thiscap is pierced by a centrallypositioned hole 5 and the material surrounding the hole is pressedupward forming a conical protrusion 6. Within the cap body is a rigidretainer disc 9. This is centrally pierced at l0 and the materialsurrounding the hole depressed to form a conical protrusion II. T

The handle l2 of brush i4 is inserted thru holes 5 and Ill with bristlesI5 depending in the fluid substance within the container, and a knob ordisc It at its top. A sealing ring I? of resilient material, such asmbber or other similar composition surrounds "brush handle [2 and isheld between the lower face of the cap top and the upper face-of theretainer disc. These parts are proportioned and arranged so thatnormally the rim 18 of disk 9 is held away from contact with the bottomof the inner face of the can by ring I1, and these parts do not contactuntil the cap is screwed down on the container neck. When this is done,however, the ring ll is compressed and its inner annular surface tightlygrips the outer surface of the brush handle. At the same time the outersurface of ring ll is tightly pressed against the adjacent innersurfaces of the conical protrusions, and in this way, a complete sealmade :around the brush handle.

A washer 2B of resilient material is fitted into the cap beneath the rimof the rigid retainer disc 9 so that it expands against the inner wallsofthe cap to secure retention. This forms a seal beneath the under faceof the outer rim portion of disc 9 and the top edge of the bottle neck3., and aids in holding the parts in position when the cap is removedfrom the bottle.

The device is primarily intended for use with containers containingviscous fluids which are to be applied by a brush; particularly thosecontaining a volatile solvent, such fluids include, for example, rubbercement. The container is filled in the usual manner, and the cap screwedonto the neck with the brush extending into the bottle almost to thebottom as indicated in dotted lines 22, Fig. 1, and the knob l6substantially flush with the cap top. The filled container are packed inthis condition. When it is desired to open and use a container, thebrush handle is first drawn up to the position shown by solid lines,Fig. 1.

The conical portion I I of disc 9 acts as a scraper and removes fluidfrom the brush handle as this is done. The handle is sealed in the ca atall times. The cap may then be unscrewed and the liquid applied by thebrush. Since the brush dips only slightly in the liquid there is noexcess clinging to it and the amount absorbed by the brush can beregulated by the extent to which the brush bristles are immersed. Afteruse the cap is replaced and the bristles are maintained immersed at thedepth desired as the liquid is consumed. Due to the fact that the bottleis completely sealed when the cap is in place there is no thickening ofliquid by evaporation and hardened cement does not cake up around theneck.

While we have illustrated and explained but one exemplary form of thedevice it is to be understood that the construction applies equally wellto cans and all other types of containers.

Many other types of brushes and liquids can be used, and still remainwithin the spirit of the invention. As above explained, the noveltyincludes the container, the cap, and the brush sealed in the cap butheld so that adjustments can be made. The disc 9 acts in a dual capacityas a solid compression element against the sealing ring I! and as ascraper to remove liquid from the brush handle as it is drawn up thruthe cap.

In view of the foregoing we wish to be limited only by the followingclaims.

We claim:

1. A brush holding and sealing cap for containers of viscous substancesincluding volatile solvents, comprising in combination with a containerhaving a threaded neck, a brush having a cylindrical handle, tufts onits lower end, and a finger disk at its upper end; a cap having a topwith a conical upward protrusion provided with a central opening and athreaded rim adapted to screw on said threaded container neck; a rigidretainer and scraper disk having arim fitted into said threaded cap rim,and a depressed conical protrusion having a central opening; a rubbersealing ring having a round radial section and a central opening,adapted to compressably receive said brush handle, fitted between saidcap top and said retainer disk and normally separating the rim of saidretainer disk from contact with the rim of the under face of said captop; a washer of resilient material fitted within a rim of said cap tohold said retainer disk in place and form a seal between the rim thereofand said container top; said brush handle extending through the centralopenings in said cap and retainer disk and the center of said sealingring, and said ring being compressed between said cap top and saidretainer disk when said cap is screwed onto said container neck so thatit is compressed radially inward against said brush handle in fluidtight relation therewith.
